Application In Locker Security System With Double Bluetooth Media Using Microcontroller And Basic Programming Language(Aplikasi Sistem Double Security Pada Locker Dengan Media Bluetooth Menggunakan Mikrokontroler Dan Bahasa Pemrograman Basic)

This study was conducted to design a security system on a locker by implementing multiple security using bluetooth media on the mobile phone and the keypad so that it can improve the security of a good value. The system is built to design, create and implement the components of a system that includes a microcontroller as process controllers, mobile phones (Bluetooth) based on android and bluetooth module HC-05 as the sender and recipient of the data series that serve as the first security in the form of a data connection and keypad as the security of both the locker system. Both security serves as input into a double security system. This system has outputs that can display information, the activation open the door and close the door and buzzer as a marker that the password is incorrect.The results showed a tool created to function properly and can be expanded to a larger scale.
